SPECIFICATION forming part of Letters Patent No. 484,305, dated October 11,1892.

Application tiled January 18. 1892. Serial No. 418,368. (No model.)

To all whom it may concern:

Be it known that I, ALBERT B. DISS, acitil zen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Wheels or Rollers for Casters and other Articles, of which the following is a specification.

In manufacturing caster-wheels it has been usual to make use of a cast-brass wheel or roller, especiallyin the better class of casters; but in practice it is found that the cast metal 1s comparatively soft, and under the strain or Weight to which the caster is usually subjected the bearing for the pivot-pin gives Way either by wear or by bending, and sometimes the hub portion of the caster-wheel breaks away, and in addition to this it is usual to turn olf the surface of the caster-wheel with deep circular recesses at each side to lessen the weight of metal necessary; but these recesses frequently become filled with dust and lint and it is difficult to clean the same because of the angular bottoms of the recesses. In some instances the caster-wheel has been made of eplrate pieces, one of which is a perforated The present invention relates to the manner hereinafter described in which the caster or other wheel is constructed, whereby great strength is obtained, the risk of injury is lessened, and the expense of the wheel is greatly decreased.

In the drawings, Figure l shows a section of a tube employed by me. Fig. 2 is a section of one of the disks. Fig. 3 is a section of the wheel with four disks after the parts have been put together, and Fig.4is a similar View of the caster-wheel with three disks.

I make use of a metal pipe or tube of a diameter corresponding to the diameter of the caster-wheel, or nearly so, and this pipe or tube is preferably of brass or other ornamental metal and is sufficiently thick for obtaining the necessary strength. The tube is cut olf into sections A, the length of each section corresponding to the width or thickness of the caster-wheel.

I make use of metal disks BB, cut out from suitable sheet metal-such as sheet-steeland having central holes of a size adapted to receive the pin or pivot of the caster-wheel, and each disk is stamped up conically, and

in making a caster-wheel two, three, four, or more of these disks B are set together with the convex sides outwardly, and these are then introduced into the tube-section A and held by suitable tools while the tube-section A is closed around theedges of the disks B, so that such tube-sectionAreceives a convex exterior surface, as shown in Figs. 3 and 4., and the edges of the disks become embedded into the tube-section A. Hence it is impossible for the disks B to escape from the tubesection forming the periphery of the casterwheel or to become loose therein,because the tube-section and its ends are contracted in diameter and become smaller at the ends than the disks. The caster-wheel thus made might be employed in the ordinary frame or jaws of. the caster or used in any other manner or in any other device, the axis or pin passing through the central holes 2 of the disks B, and the conical shape which has been given to the disks B causes the bearings of such disks upon the-pivot-pin to be in line or slightlybeyond the edges of the tube'section A.

When only two disks-such as shown in Fig. Z-are employed, the angles between the surfaces of the disk and the interior of the tube-section might be lled with solder or soft metal. Usually it is advantageous to employ three disks, as shown in Fig. 4, the central disk being thickest and slightly largest, or four disks may be used, as in Fig. 3,the two innerdisks being slightly thelargest. The disks are preferably cleaned and polished before placing them in the tube-section. This may be done by a rumbler or other appliance. After the parts are put together the wheels may be dipped in a proper plating solutionsuch as brass or bronze solution-to coat the outer surfaces of the wheels, so as to be of uniform color, and they may then be buffed or polished. Wheels made as aforesaid are much stronger than the wheels heretofore oonstructed, and with brass or other ornamental metal they are much cheaper than those heretofore made.

I claim as my invention- 1.
